When I told my dad I was worried about my hair loss (who is an unashamed NW7) he laughed at me. He and every other family member just told me it was something that men have to deal with... me being only 16 and already a NW2 I found that hard to accept. I begged and pleaded to see a doctor for 2 years before he finally caved and took us to our GP, who is also an unashamed NW7. By then I was already a NW3 heading into NW4 territory. Him and my dad shared a laugh as I explained my concerns, then he examined my head for all of 10 seconds and told me I should take a zinc supplement and sent me on my way. No mention of finasteride, minoxidil, nothing at all.
My sister and my aunts all laughed at me as well. I mean, I was always pretty femme with me being trans and all, so me losing my hair was like the ultimate "HAHA!" moment to all those disapproving people. And then there was all the unsolicited advice on what I should do (stuff like "just shave it bro", "hit the gym bro", etc.)
The sad truth is that you're a minority in feeling that way. Most boys grow up with the notion that their problems are irrelevant and no one cares being hammered into their heads, so they internalize them.
